[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell module in which a frame is mounted around the periphery of a solar cell module body, and a plurality of such modules are arranged side by side on a sloped roof using a pedestal or the like, and a solar power generation is performed. And a method of installing the power generation device on a sloping roof, and an intermediate cradle used to support a solar cell module disposed adjacent to the roof in the inclination direction in the power generation device. .

[0002]

2. Description of the Related Art As shown in FIGS. 14 and 15, a power generating apparatus installed on a sloped roof to generate photovoltaic power has rail-shaped horizontal mounts 1 to 4 on a roof 8 intersecting the direction of the slope. After fixing each along the direction, a plurality of framed solar cell modules 5 are installed over the horizontal mounts 1, 2, 2, 3, 3 and 4 adjacent to the roof 8 in the inclination direction. . The solar cell module 5 is provided with a frame member made of an extruded material (only the eaves side frame member 7a and the ridge side frame member 7b are shown in FIG. 15) around the periphery of the rectangular solar cell module main body 6, respectively. It becomes. In FIG. 14, reference numeral 8a denotes a tile rod of the tiled roof 8.

Each solar cell module 5 has a frame member 7a on the eaves side of a horizontal mount (horizontal mount 1 in FIG. 14) which is relatively disposed on the eaves side among horizontal mounts adjacent to the roof 8 in the inclination direction. After being superimposed on the upper surface, the ridge side frame member 7b is superimposed on the upper surface of a horizontal gantry (horizontal gantry 2 in FIG. 14) which is relatively arranged on the ridge side, and then a pair of upper and lower clamps and bolts and nuts for tightening them are provided. The frame members 7a and 7b are individually connected to the respective horizontal mounts by using a plurality of connecting devices 9 having the following. 14 and FIG. 14, reference numeral 10 denotes an end cover attached to the end horizontal frames 1, 4 arranged on the eaves side or the ridge side of the power generating device, and 11 denotes other intermediate horizontal frames 2, 3. It is a center cover that is attached to the vehicle.

Conventionally, in addition to stacking and framing the frame members 7a and 7b on a horizontal frame adjacent to the roof 8 in the inclination direction as described above, the frame member mounted around the solar cell module 5 Of the pair of side frame members, to obtain the strength necessary to withstand the downward load applied by strong wind,
In addition to being formed with a large height dimension, the height dimensions of the other upper and lower frame members are also made larger in accordance with the size of these side frame members.

[0005] For this reason, the installation thickness H of the conventional power generator is as large as about 87 mm. Therefore, when tiles are arranged around the power generator, the step between the tile surface and the power generator is large, and the appearance of the roof is reduced. Easy to damage. In addition, as described above, the roof 8 is provided by using a plurality of connecting devices 9 for each solar cell module 5.
It requires time and effort to connect to the horizontal stand adjacent in the direction of inclination, so that the workability of attaching to the roof is not good. Moreover, as described above, since the height dimension (thickness) of the frame material of the solar cell module 5 is large, the amount of material used for the frame material is large. is there.

On the other hand, in a solar cell module mount that is installed not on a roof but on the ground, a solar cell module having no frame material attached to its periphery is connected to an upper horizontal mount having a diagonally downwardly opening groove and an obliquely upward There is known a technique of installing the lower gantry having a groove that opens in a so-called kendon system (Japanese Utility Model No. 8-3023).
Reference).

In the kendon method described in this publication, the entire upper edge portion of the solar cell module is inserted obliquely upward from the lower side into the groove of the upper horizontal mount, and then the entire solar cell module is mounted on the upper horizontal mount as a center. Side, the entire lower edge of this module is brought into close proximity to the groove of the lower horizontal frame, and then the entire solar cell module is moved obliquely downward.
That is. Thus, the entire lower edge of the solar cell module is inserted into the groove of the lower horizontal mount while maintaining the insertion of the upper horizontal mount into the groove. As described above, the solar cell module can be installed over the upper and lower horizontal mounts.

[0008] According to the technique described in this publication, since the horizontal mount and the solar cell module do not stack, if applied to the installation of a solar cell module on a roof, the structure shown in FIGS. Is also excellent in that the installation height can be reduced. However, there is still no difference in that the solar cell module itself obtains the withstand pressure in a strong wind. For this reason, the thickness of the entire solar cell module is large, and accordingly, the thickness of the horizontal mount needs to be made large, resulting in high cost. Therefore, it is desired to improve these points to make the solar cell module and the power generation device thinner, particularly for those installed on a roof.

In addition, according to the technology described in the above publication, the entire upper edge of the solar cell module is inserted into the groove of the upper horizontal mount. Therefore, when the entire upper edge is inserted into the groove of the upper horizontal mount. In addition, the two are easy to compete with each other, and it is also necessary to reduce the insertion angle of the solar cell module, so that the workability of mounting the solar cell module by the kendon method is not good. Further, as described above, in the configuration in which the entire thickness of the upper edge portion of the solar cell module is inserted into the groove of the upper horizontal mount, the turning radius connecting the pivot point of the solar cell module to the upper corner of the lower edge portion is provided. Is big. Therefore, when the space between the upper and lower horizontal mounts is set as small as possible in order to reduce the installation space of the power generating device, the module is rotated so that the lower edge of the solar cell module faces the groove of the lower horizontal mount. In addition, the lower edge of the solar cell module easily hits the upper wall of the groove of the lower horizontal stand, and the workability of installing the solar cell module by the kendon method may be greatly reduced.

It is assumed that the solar cell module is installed in a swift manner between the lower frame and the lower horizontal frame having an upward groove.

The first aspect of the present invention is the first aspect of the present invention.
In order to solve the problem of, in the upper frame material that is inserted into the downward groove of the frame material and is supported by the upper horizontal frame,

In the present invention and each of the following inventions, the solar cell module body has an amorphous photoelectric conversion part having an amorphous semiconductor, a crystalline photoelectric conversion part having a single crystal semiconductor or a polycrystalline semiconductor having a polycrystalline semiconductor. Also, as the frame material to be attached to the peripheral part of the module body, use a mold material obtained by molding a metal such as an aluminum alloy by extrusion molding or a molded product of a synthetic resin. Can be. In the present invention and each of the following inventions, the first insertion protrusion integrally projecting from the upper frame member is, particularly, an upper side, especially an upper side, at an intermediate height position in a thickness direction of the upper frame member. It is preferable to protrude at a height of about 1/3 from
Also, the first insertion projection is preferably as thin as possible within a range that can maintain the required strength, and for example, it is desirable that the first insertion projection be a flange having the same thickness as the thickness of each part of the upper frame member. Further, in the present invention, the lower frame member has the second insertion convex portion as in the second aspect of the present invention, and the convex portion is fitted into the groove of the lower horizontal base, so that the lower frame member can be installed by the karting system. You may also do
The present invention may be carried out without providing the second insertion protrusion on the lower frame member, and the entire thickness of the lower frame member may be inserted into the upward groove of the lower horizontal gantry so that the lower frame member can be installed by the karting method. . Further, the solar cell module of the present invention is not limited to a solar cell module installed on a sloped roof, but can be applied to a solar cell module installed on a flat roof or a ground surface for photovoltaic power generation.

According to the first aspect of the present invention, in order to install a solar cell module between adjacent horizontal mounts in a caddy manner, first, a first insertion projection integrally projecting from an upper frame member of the module is provided. Insert into the downward groove of the upper horizontal base that opens diagonally downward. Next, the lower frame member is opened obliquely upward by rotating the entire solar cell module so that the lower frame member approaches the lower horizontal frame member, with the upper horizontal frame as a pivot point. The lower horizontal stand is made to face and close to the upward groove. Thereafter, the entire solar cell module is moved obliquely downward by its own weight, and at least a part of the lower frame member is inserted into the upward groove while maintaining the insertion of the first insertion projection into the downward groove.

According to the above-described procedure, the solar cell modules can be arranged over the adjacent horizontal mounts separated vertically.
In this state, since the first insertion protrusion is positioned so as to be hooked on the groove upper wall of the downward groove of the first insertion protrusion, it is prevented that the solar cell module comes off from the upper horizontal pedestal. Since the frame member is positioned so as to be caught in the upward groove of the lower horizontal cradle, the solar cell module is prevented from being detached from the lower horizontal cradle.

[0019] In the installation operation using the kendon method, the insertion of the upper frame member of the solar cell module into the downward groove of the upper horizontal frame does not involve inserting the entire thickness of the upper frame member, but rather involves a much greater thickness. Is performed by inserting the thin first insertion projection, the first insertion projection and the downward groove are less likely to compete with each other, and the insertion angle of the solar cell module can be increased. Insertion of the first insertion projection can be facilitated. Further, since the first insertion protrusion is located at a middle position in the height direction of the upper frame member, the length connecting the tip of the first insertion protrusion to the outermost end of the lower frame member in a straight line is equal to the length of the upper frame member. Is shorter than the length of a similar straight line when the entire thickness is inserted into the downward groove. Therefore, even when the space between the adjacent horizontal mounts is narrowed, when the entire solar cell module is rotated so that the lower frame material approaches the lower horizontal mount side, the lower frame material is , It is easy to carry out the work easily. Further, as described above, since the entire thickness of the upper frame member is not inserted into the downward groove of the horizontal frame, the height of the horizontal frame having the downward groove can be reduced.

In carrying out the invention of claim 1,
As in the invention of claim 2, the lower frame member is inserted and arranged in the upward groove so as to protrude from a height position in the middle of the thickness direction of the frame material and to be hooked on a groove upper wall of the upward groove. The second insertion projection may be provided integrally, and the second insertion projection may be shorter than the width of the first insertion projection.

In the invention of the second aspect and the following invention, the second insertion projection integrally projecting from the lower frame member is particularly provided at a middle height position in the thickness direction of the lower frame member. , From the upper side, particularly from the upper side, it is preferable to protrude at a height of about 1/3, and it is desirable that the second insertion projection be provided at the same height as the first insertion projection. Moreover, the second insertion projection is preferably as thin as possible within a range that can maintain the required strength, and is desirably a flange having a thickness approximately equal to the thickness of each part of the lower frame member, for example.

According to the second aspect of the present invention, in the work of installing the solar cell module by the kendon method between adjacent horizontal mounts, the lower frame material of the solar cell module is inserted into the upward groove of the lower horizontal mount. Since the insertion is performed not by inserting the entire thickness of the lower frame member but by inserting the second insertion convex portion having a much smaller thickness, the second insertion convex portion and the lower horizontal frame are connected to each other. Competition is less likely, and the insertion of the second insertion protrusion into the upward groove of the lower horizontal base can be facilitated. Therefore, it is possible to improve the installation workability of the solar cell module by the kendon method. Then, after the installation of the solar cell module is completed, the second insertion protrusion of the lower frame member is inserted so as to be hooked on the groove upper wall of the upward groove of the lower horizontal frame.
The solar cell module is prevented from coming off from the lower horizontal stand. Further, since the second insertion projection is shorter than the first insertion projection, the cost can be reduced.

According to a third aspect of the present invention, there is provided a power generating apparatus which is fixed on a roof so as to extend in a direction intersecting the inclination direction of the roof and open obliquely downward. An upper horizontal gantry having a groove, a lower horizontal gantry having an upward groove which is disposed on the roof in parallel with the upper horizontal gantry and is spaced apart below the upper horizontal gantry, and opens obliquely upward; A frame member is attached to the periphery of the rectangular solar cell module body, and the lower frame member is inserted into the downward groove of the frame member and inserted into the upward groove and supported by the upper horizontal frame and the lower frame member. At least the upper frame member of the lower frame member supported by the side frame is projected downward from the intermediate height position of the frame member in the thickness direction and is hooked on the groove upper wall of the downward groove. First inserted into the groove
A solar cell module having an insertion convex portion integrally and being installed between the upper horizontal frame and the lower horizontal frame by a swift method.

In the invention according to claim 3 and the following invention, the upper horizontal frame and the lower horizontal frame are installed on a roof eave (inclined).
Which are adjacent to each other in the direction, and these are mold members obtained by molding a metal such as an aluminum alloy by extrusion molding or the like,
Alternatively, it can be formed of a synthetic resin molded product or the like.

According to the third aspect of the present invention, in order to install a solar cell module by a swift method over an upper horizontal frame and a lower horizontal frame which are adjacent to each other in a roof eaves direction,
First, a first insertion protrusion integrally projecting from an upper frame member of the module is inserted into a downward groove of an upper horizontal base that is opened obliquely downward. Next, the lower frame member is opened obliquely upward by rotating the entire solar cell module so that the lower frame member approaches the lower horizontal frame member, with the upper horizontal frame as a pivot point. The lower horizontal stand is made to face and close to the upward groove. Thereafter, the entire solar cell module is moved obliquely downward, that is, toward the eaves side by its own weight, and at least a part of the lower frame member is inserted into the upward groove while maintaining the insertion of the first insertion protrusion into the downward groove. Let it.

According to the above-described procedure, the solar cell modules can be arranged over the horizontal stand adjacent in the building eaves direction. In this state, since the first insertion protrusion is positioned so as to be hooked on the groove upper wall of the downward groove of the first insertion protrusion, it is prevented that the solar cell module comes off from the upper horizontal pedestal. Since the frame member is positioned so as to be caught in the upward groove of the lower horizontal cradle, the solar cell module is prevented from being detached from the lower horizontal cradle.

In the installation operation by the above-mentioned kendon method, the insertion of the upper frame member of the solar cell module into the downward groove of the upper horizontal frame does not involve inserting the entire thickness of the upper frame member, but rather involves a much larger thickness. Is performed by inserting the thin first insertion protrusion, the first insertion protrusion and the downward groove are less likely to compete with each other, and the insertion angle of the solar cell module can be increased. Insertion of the first insertion projection can be facilitated. Further, since the first insertion protrusion is located at a middle position in the height direction of the upper frame member, the length connecting the tip of the first insertion protrusion to the outermost end of the lower frame member in a straight line is equal to the length of the upper frame member. Is shorter than the length of a similar straight line when the entire thickness is inserted into the downward groove. Therefore, even when the space between the upper horizontal frame and the lower horizontal frame adjacent in the ridge eaves direction is narrowed, when the entire solar cell module is rotated so that the lower frame material thereof approaches the lower horizontal frame side. In addition, since the lower frame member hardly hits the lower horizontal stand, the work can be easily performed. Further, as described above, since the entire thickness of the upper frame material is not inserted into the downward groove of the upper horizontal frame, the width of the downward groove is reduced, and therefore, the height of the upper horizontal frame having this groove is reduced. Can be lowered.

Similarly, in order to solve the second problem, a power generator according to the invention according to claim 4 is fixed on a roof so as to extend in a direction intersecting the inclination direction of the roof and to be inclined downward. An upper horizontal frame having a downward groove to be opened, and a lower horizontal frame having an upward groove which is arranged on the roof in parallel with the upper horizontal frame at a distance below the upper horizontal frame and opens obliquely upward. The frame and the frame material are respectively mounted on the periphery of the rectangular solar cell module main body, and the upper frame material inserted into the downward groove and supported by the upper horizontal frame has a height in the middle of the thickness direction of the frame material. A first insertion protrusion that is inserted into the downward groove so as to be protruded from a position and hooked on a groove upper wall of the downward groove; and is integrally inserted into the upward groove and supported by the lower horizontal stand. The lower frame material to be Is inserted into the upward groove so as to be hooked on the groove upper wall of the upward groove and protruded from the height position of the upward groove, and furthermore, the second insertion convex portion shorter than the output width of the first insertion convex portion is integrally formed. And a solar cell module installed between the upper horizontal frame and the lower horizontal frame by a swift method.

In the present invention, in the work of installing the solar cell module by the kendon method between vertically adjacent horizontal mounts, the upper frame material of the solar cell module is inserted into the downward groove of the upper horizontal mount. This is performed in the same procedure as in step 3. Therefore, the first insertion projection and the downward groove are less likely to compete with each other, and the insertion angle of the solar cell module can be made large, so that the insertion of the first insertion projection into the downward groove can be facilitated, and the adjacent vertical Even when the space between the horizontal mounts is narrowed, the lower frame material can be less likely to hit the lower horizontal mount when the entire solar cell module is rotated so that the lower frame material thereof approaches the lower horizontal mount side. . Also, the insertion of the lower frame member of the solar cell module into the upward groove of the lower horizontal frame does not involve inserting the entire thickness of the lower frame member, but the second insertion projection having a much smaller thickness. Is inserted, the second insertion protrusion and the lower horizontal frame are less likely to compete with each other, and the insertion of the second insertion protrusion into the upward groove of the lower horizontal frame can be facilitated. And after the installation of the solar cell module is completed,
Since the second insertion protrusion of the lower frame member is inserted so as to be hooked on the groove upper wall of the upward groove of the lower horizontal base, it is prevented that the solar cell module comes off from the lower horizontal base.

Therefore, in the invention of claim 4,
The installation workability of the solar cell module by the kendon method can be improved. Also, the entire thickness of the upper frame member is not inserted into the downward groove of the upper horizontal frame, and the entire thickness of the lower frame member is not inserted into the upward groove of the lower horizontal frame. The height of the upper and lower horizontal mounts can be reduced without being limited by the thickness of the frame material. Further, since the second insertion projection is shorter than the first insertion projection, the cost can be reduced.

According to a fourth aspect of the present invention, as in the fifth aspect of the present invention, the second insertion convex portion is formed of a convex portion base and a rising portion which rises upward from the convex portion base. Is preferably screwed into the groove upper wall of the lower horizontal frame from above.

In the present invention, a screw is screwed from above into the upper wall of the groove of the lower horizontal mount in a state where the solar cell module is installed between the adjacent upper and lower horizontal mounts by the kendon method. The projection base of the second insertion projection of the side frame is pressed downward. For this reason, rattling of the solar cell module installed by the kendon method can be prevented.
In addition, since the screw inserted is disposed so as to be hooked on the rising portion of the second insertion projection, even if the solar cell module is moved in the direction of the upper horizontal pedestal for some reason, the screw and the rising portion may be used. The movement can be hindered.

In practicing any one of the third to fifth aspects of the present invention, as in the invention of the sixth aspect, the upper frame member of the solar water battery module supported by the upper horizontal base is provided. It is preferable that a holding member that holds down the solar cell module supported by the holding member from above in the thickness direction is attached to the lower horizontal base while attaching a holding member that holds down the holding member from above in the thickness direction.

In the present invention, the holding member can be formed of a mold material obtained by molding a metal such as an aluminum alloy by extrusion or the like, or a molded product of a synthetic resin. The holding member is attached to the upper frame member and the lower frame member by screwing, or by using a claw engagement between a locking claw and a claw receiving portion on which the locking claw is hooked without using a screw. Is also good.

According to the sixth aspect of the present invention, the portions of the upper frame member and the lower frame member of the solar cell module protruding from the respective grooves of the upper and lower horizontal frames are pressed from above by the pressing members. It is possible to increase the installation strength of the solar cell modules mounted over the horizontal stand adjacent to the eaves ridge direction. In addition, when the holding member covers the entire upper surface of the horizontal gantry, the appearance of the power generator can be improved.

In practicing any one of the third to sixth aspects of the present invention, as in the seventh aspect of the present invention, the longitudinally intermediate portions of a pair of side frame members parallel to each other among the frame members are formed as described above. It is preferable that an auxiliary rail supported from the rear side of the solar cell module between the upper horizontal frame and the lower horizontal frame is fixed to the roof. In the present invention, one or more auxiliary rails can be provided between the horizontal mounts adjacent to each other in the eave direction.

In the invention according to claim 7, the intermediate portion of the solar cell module in the eaves ridge direction is supported by the auxiliary rail,
Since it is possible to improve the withstand pressure in a strong wind, it is not necessary to obtain the withstand pressure performance by the side frame material of the solar cell module itself. Accordingly, each frame member and each horizontal mount can be made thinner, so that the cost can be reduced and the height of the power generator set on the roof can be reduced.

In practicing any one of the third to seventh aspects of the present invention, as in the eighth aspect of the present invention, an array of a plurality of solar cell module groups arranged so as to intersect in the inclination direction of the roof. It is preferable to arrange stoppers on both sides in the direction. In the present invention, the stopper can be fixed to a roof, a horizontal mount, an auxiliary rail, or the like by screwing or the like.

According to the eighth aspect of the present invention, as described above, a group of solar cell modules installed on the roof by the kendon method and arranged in the longitudinal direction of the horizontal mount are arranged on both sides of the group. The stoppers can be simultaneously stopped in the longitudinal direction of the horizontal stand. Therefore, it is not necessary to stop all the individual solar cell modules individually, and also in the case where the individual detent means for some of the solar cell modules are used in combination in order to make the detent more reliable. Therefore, the number of places where the solar cell module stops moving in the longitudinal direction of the horizontal mount can be significantly reduced.

In practicing any one of the third to eighth aspects of the present invention, as in the ninth aspect of the present invention, the depth of the upper horizontal base from the downward groove of the downward groove to the bottom of the lower horizontal base is reduced. The groove bottom wall of the lower horizontal stand may be protruded such that the distance to the tip of the wall is shorter than the length from the tip of the first insertion projection to the root of the second insertion projection.

According to the present invention, the solar cell module is arranged such that the upper frame member is inserted into the downward groove of the upper horizontal base, and the solar cell module is moved toward the lower horizontal base with the upper horizontal base as a fulcrum. The lower frame material can be reliably mounted on the groove bottom wall of the lower horizontal gantry without the lower frame material being caught on the groove bottom wall of the lower horizontal gantry during the rotation.

In practicing any one of the third to ninth aspects, as in the tenth aspect, the frame is made of metal and one of the left and right side frame members is provided with a male mold. Attach the insulated wire with the connection terminal at the tip,
It is preferable to attach an insulated wire having a female connection terminal at the end to the other side frame member, and electrically connect the frames of the solar cell module adjacent in the lateral direction by fitting the male and female terminals into male and female terminals. .

In the present invention, when the ground is taken,
The electrically insulated wires corresponding to each other attached to the side frame members of the solar cell modules adjacent in the side-by-side direction can be electrically easily connected to each other by the male and female fittings of the male connection terminal and the female connection terminal. Can be connected to

In practicing the tenth aspect of the present invention, it is preferable that the left and right side frame members and the insulated wires attached thereto are arranged point-symmetrically as in the eleventh aspect of the present invention.

In the present invention, since the insulated wires are mounted at the same position on the left and right side frame members of the solar cell module, the processing of the wire mounting portions for the left and right side frame members can be performed in the same manner. Side frame material can be shared.

According to a twelfth aspect of the present invention, there is provided a method for installing a power generating apparatus, comprising: an upper horizontal pedestal having a downward groove which is opened obliquely downward; After fixing each of the lower horizontal gantry having an upward groove which is arranged parallel to the side and is opened obliquely upward, on the roof along a direction intersecting with the inclination direction of the roof, A frame material is attached to the peripheral portion of the shape solar cell module body, and the upper frame material and the upper frame which are inserted into the downward grooves and are supported by the upper horizontal gantry are inserted into the upward grooves. At least the upper frame material of the lower frame material supported by the lower horizontal frame, and protruding from a height position intermediate in the thickness direction of the frame material so as to be hooked on the groove upper wall of the downward groove. The first inserted into the downward groove A plurality of solar cell modules provided integrally with the convex portions are installed one after another over the upper horizontal frame and the lower horizontal frame by a tentative method, and each of the solar cell modules intersects with the inclination direction of the roof. Then, the solar cell modules located at both ends in the arrangement direction of each of the solar cell module groups arranged in a direction intersecting with the inclination direction of the roof are respectively stopped.

In the installation work of the solar cell module on the roof by the tentative method according to the method of the present invention, the insertion of the upper frame material of the solar cell module into the downward groove of the upper horizontal frame is performed by removing the entire thickness of the upper frame material. Since the insertion is performed by inserting the first insertion projection, which is much thinner than the insertion, the first insertion projection and the downward groove are less likely to compete with each other, and the insertion angle of the solar cell module is reduced. Since it can be large, it is easy to insert the first insertion projection into the downward groove. Further, since the first insertion protrusion is located at a middle position in the height direction of the upper frame member, the length connecting the tip of the first insertion protrusion to the outermost end of the lower frame member in a straight line is equal to the length of the upper frame member. Is shorter than the length of a similar straight line when the entire thickness is inserted into the downward groove. Therefore, even when the space between the adjacent horizontal mounts is narrowed, when the entire solar cell module is rotated so that the lower frame material approaches the lower horizontal mount side, the lower frame material is , It is easy to carry out the work easily. In addition, by stopping a group of solar cell modules arranged in the longitudinal direction of the horizontal stand, the solar cell modules located at both ends in the arrangement direction of the group, the other solar cell modules can be moved in the longitudinal direction of the lateral stand. Since it is possible to stop the movement at the same time, it is not necessary to stop all the solar cell modules individually. Therefore, it is possible to improve the workability of installing the power generator having the solar cell module supported on the horizontal mount by the kendon method on the roof.

[0048] Similarly, in order to solve the third problem, a method for installing a power generating apparatus according to a thirteenth aspect of the present invention is directed to an upper horizontal pedestal having a downward groove that opens obliquely downward, and an upper horizontal pedestal. Each of the lower horizontal mounts having an upward groove which is disposed in parallel and separated from the lower side and which opens obliquely upward, is fixed on the roof along a direction intersecting with the inclination direction of the roof. After fixing the auxiliary rail to the roof positioned between the upper horizontal frame and the lower horizontal frame, frame members are respectively mounted on the periphery of the rectangular solar cell module body, and Of the upper frame material inserted into the downward groove and supported by the upper horizontal frame and the lower frame material inserted into the upward groove and supported by the lower horizontal frame, , The height in the middle of the thickness of this frame material A plurality of solar cell modules integrally provided with a first insertion protrusion inserted and disposed in the downward groove so as to be protruded from the device and to be hooked on a groove upper wall of the downward groove; Along the base and the lower horizontal mount, one after the other, the middle part in the longitudinal direction of a pair of parallel side frame members of these modules is supported by the auxiliary rail from the back side of each of the solar cell modules, The battery modules are arranged side by side on the roof, and then stoppers are respectively arranged on both sides of the solar cell module groups arranged in a direction intersecting with the inclination direction of the roof, and the respective stoppers are arranged on each of the horizontal mounts. A holding member for holding the upper frame material or the lower frame material of the solar hot water battery module supported from above in the thickness direction from above.

According to the present invention, in the installation operation of the solar cell module on the roof by the tentative method, the insertion of the upper frame material of the solar cell module into the downward groove of the upper horizontal stand is performed by removing the entire thickness of the upper frame material. Instead of inserting
Since the insertion is performed by inserting the first insertion projection, which is much thinner than that, the first insertion projection and the downward groove are less likely to compete with each other, and the insertion angle of the solar cell module can be increased. The insertion of the first insertion projection into the downward groove can be facilitated. Further, since the first insertion protrusion is located at a middle position in the height direction of the upper frame member, the length connecting the tip of the first insertion protrusion to the outermost end of the lower frame member in a straight line is equal to the length of the upper frame member. Is shorter than the length of a similar straight line when the entire thickness is inserted into the downward groove. Therefore, even when the space between the adjacent horizontal mounts is narrowed, when the entire solar cell module is rotated so that the lower frame material approaches the lower horizontal mount side, the lower frame material is , It is easy to carry out the work easily. In addition, by stopping a group of solar cell modules arranged in the longitudinal direction of the horizontal stand, the solar cell modules located at both ends in the arrangement direction of the group, the other solar cell modules can be moved in the longitudinal direction of the lateral stand. Since it is possible to stop the movement at the same time, it is not necessary to stop all the solar cell modules individually. Therefore, it is possible to improve the workability of installing the power generator having the solar cell module supported on the horizontal mount by the kendon method on the roof. Furthermore, since the parts protruding from the grooves of the upper frame and the lower frame of the upper frame material and the lower frame material of the solar cell module are pressed from above with the pressing members, the mounting is performed over the horizontal frame adjacent to the eaves ridge direction. The installation strength of the obtained solar cell module can be increased.

According to a fourteenth aspect of the present invention, there is provided an intermediate horizontal mount for supporting a solar cell module adjacent to the roof in the inclination direction, wherein the intermediate horizontal mount is an eaves side. A downward groove that opens diagonally downward toward
Upward grooves that open obliquely upward toward the ridge side are provided in a back-to-back state, and at least the height dimension of the downward grooves of these two grooves is smaller than the thickness of the solar cell module, and The length of the groove upper wall of the groove is shorter than the length of the groove bottom wall of the downward groove.

The intermediate horizontal mount of the present invention is capable of inserting and supporting the lower frame portion of the solar cell module disposed on the ridge side into the upward groove, and is provided so as to be opposed to the upward groove. The upper frame portion of the solar cell module arranged adjacent to the eaves side of the module can be inserted and supported in the downward groove, so that it is suitable for installing the solar cell module adjacent to the eaves direction in a fast-moving manner. . In addition, since the height dimension of at least the downward groove is smaller than the thickness of the solar cell module, a solar cell module having an upper frame member having an insertion projection projecting at an intermediate height position in the thickness direction of the upper frame member is provided. Suitable for installation by the kendon method. In addition, since the length of the upper wall of the downward groove is shorter than the length of the lower wall of the downward groove, the insertion frontage (opening) of the downward groove into which the upper frame member provided with the insertion protrusion is inserted. And the angle (insertion angle) between the roof surface and the solar cell module can be increased, so that the upper frame member can be easily inserted into the downward groove.

However, the provision of the cushioning material as in the present embodiment is advantageous in that the amount of the rubber plate 76 used can be reduced and the cost can be reduced. .

As shown in FIG. 1, the auxiliary rail 31
It is located between the upper horizontal frame and the lower horizontal frame adjacent to the roof 21 in the eaves ridge direction, and is attached to the roof 21 in parallel with these horizontal frames. Therefore, the auxiliary rail 31 is
The tiles 22 are arranged orthogonally to the tile bar 22 between 6, 27, between the horizontal mounts 27, 28, and between the horizontal mounts 28, 29, respectively. Each of these auxiliary rails 31 is an extruded shape material of an aluminum alloy, and has a screwing flange 31a that extends integrally in the width direction on both sides of the hollow portion as shown in FIG. The auxiliary rail 31 is fixed on the roof 21 via screws (not shown) which are screwed into the tile rod 22 through these flanges 31a.

The upper surface of the auxiliary rail 31 and the groove bottom wall 41
The separation height A (see FIG. 2) of the solar cell module 30 with respect to the tile rod 22 defined by the upper surfaces of the b, 45b, 51b, and 52b is such that the insulated wire (not shown) can be inserted, and both wires can be inserted. The connector at the tip of is set to a size that cannot be inserted. Thereby, the height of the power generator 25 on the roof 21 is made as low as possible, and the height (thickness) dimension of each of the horizontal mounts 26 to 29 and each of the auxiliary rails 31 is reduced to reduce the cost.

The holding member 32 is made of an extruded aluminum alloy material.
The length of the solar cell module 30 is the same as the width of the solar cell module 30 as shown in FIG. These holding members 32
Has a frame material pressing portion 81 on both sides in the width direction as representatively shown in FIG. 5, and a pair of locking claws 82 to be hooked on the claw receiving portion 54a between them integrally. are doing. Each pressing member 32 covers the member receiving portion 54 of the horizontal gantry 26 to 29 and presses from above, and the locking claw 82 is hooked on the claw receiving portion 54a, so that these are respectively attached to the horizontal gantry 26 to 29. Covered and installed.

A pair of stoppers 33 made of an extruded aluminum alloy is a bar having an L-shaped cross section as shown in FIG. Photovoltaic modules 3 arranged orthogonally
Group 0 is attached to the roof 21 with both sides in the horizontal direction. That is, in the present embodiment, the stoppers 33 are individually connected to the respective auxiliary rails 30 by the screws 85, respectively, so that both ends in the horizontal arrangement direction of the group of the solar cell modules 30 arranged orthogonally to the inclination direction of the roof 21. The solar cell module 30 located at the position is stopped and attached to the roof 21.

Next, the procedure for attaching and constructing the power generator 25 on the roof 21 will be described.

First, a plurality of horizontal mounts, that is, horizontal mounts 26, 2 serving as end rails on the ridge side and the eaves side, are placed on the roof 21.
9 and the horizontal mounts 27 and 28 serving as intermediate rails are arranged and fixed in parallel with each other at predetermined intervals along the inclination direction of the roof 21, and between the horizontal mounts adjacent to each other along the inclination direction of the roof 21. The auxiliary rails 31 are respectively arranged in a posture parallel to each of the horizontal mounts, and they are fixed to the roof 21. The horizontal mounts 26 to 29 and the auxiliary rail 31 are fixed by screwing to the tile bar 22 at right angles to the inclination direction of the roof 21.

Next, the solar cell module 3 extends over the upper horizontal frame and the lower horizontal frame adjacent to the roof 21 in the inclination direction.
0s are set one after another according to the ken system. That is, a case where the solar cell module 30 is installed between the lower horizontal frame 29 forming the eaves-side end rail and the upper horizontal frame 28 forming the intermediate rail and adjacent to the lower horizontal frame 29 will be described below as a representative. .

First, as shown in a two-dot chain line in FIG. 2 and in FIG. 6, the solar cell module 30 is tilted in the opposite direction to the tilt direction of the roof 21, and the first insertion projecting integrally with the upper frame member 63. Upper horizontal stand 28 that opens projection 71 diagonally downward
Into the downward groove 51. This insertion direction is indicated by an arrow C in FIGS. Next, the solar cell module 30 is rotated so that the lower frame member 64 approaches the lower horizontal frame 29 using the upper horizontal frame 28 as a rotation fulcrum. This rotation direction is indicated by an arrow D in FIGS. By this rotation operation, the lower horizontal frame 2 in which the lower frame member 64 is opened obliquely upward.
9 is opposed to the upward groove 45. Thereafter, the entire solar cell module 30 is moved obliquely downward along the inclination of the roof 21 by its own weight, and the first insertion projection 71 is inserted into the downward groove 51 of the lower frame member 66 while maintaining the insertion. 2 Insert the insertion protrusion 75 into the upward groove 45. The movement of the solar cell module 30 in this case may be assisted by hand, and the movement direction is indicated by an arrow E in FIGS. 2 and 6. According to the above procedure, the solar cell module 30 is disposed over the horizontal mounts 28 and 29 adjacent to each other with a vertical separation.

All of the solar cell modules 30 are successively arranged on the roof 21 by the above-described stiffening method. Each of the solar cell modules 30 thus arranged is supported by an auxiliary rail 31 from the back side thereof. That is, a substantially central portion in the longitudinal direction of both side frame members 65 and 66 of each solar cell module 30 is placed on the auxiliary rail 31. Further, adjacent solar cell modules 30 intersecting with the inclination direction of the roof 21 are adjacent to the side frame members 65 and 6.
6 are arranged in the lateral direction of the roof 21 in contact with each other (see FIG. 3).

After arranging the respective solar cell modules 30 as described above, the stoppers 33 are arranged on both sides of the solar cell modules 30 arranged in the horizontal direction intersecting with the inclination direction of the roof 21, respectively. These stoppers 3
3 are screwed to the auxiliary rails 31, respectively. Thereby,
The group of solar cell modules 30 is stopped in the lateral direction of the roof 21.

Finally, a holding member 32 is attached to each of the horizontal frames 26 to 29 so as to hide them. These holding members 32 are placed on appropriate positions for the respective horizontal mounts 26 to 29, and then pressurized by hand from above, and at the same time, the locking claws 82 are attached to the claw receiving portions 54a of the horizontal mounts 26 to 29. This is done by locking. The attachment of the holding members 32 to the horizontal frames 26 to 29 can be performed prior to the attachment of the stopper 33.

The power generator 25 is installed on the roof 21 by the above procedure. In the installation operation of the solar cell module 30 according to the kendon method performed at the time of this installation, as described above, the insertion of the upper frame member 63 of the solar cell module 30 into the downward groove 41 or 51 of the upper horizontal base. Instead of inserting the entire thickness of the upper frame member 63, the first insertion projection 71, which is much thinner, is inserted. Therefore, the first insertion protrusion 71 is formed by the groove upper wall 41 of the downward groove 41.
a or the lower groove 51 is less likely to compete with the groove upper wall 51a, and the first insertion protrusion 71 can be easily inserted into the downward groove 41 or 51.

In addition, the first insertion projection 71 is formed by the upper frame member 63.
At the intermediate position in the height direction of the first insertion protrusion 7
The length connecting a straight line from the front end of the first frame member 1 to the outermost end of the lower frame member 64, that is, the front end of the second insertion convex portion 75 in this embodiment, is equal to the length of the downward groove 41 or 51 through the entire thickness of the lower frame member 64. Is shorter than a similar straight line when inserted into Therefore, even if the space between the horizontal mounts adjacent to the roof 21 in the inclination direction is narrowed, the solar cell module 30 can be moved to the lower frame member 6.
4 is rotated so as to approach the lower horizontal frame, the second insertion convex portion 75 of the lower frame member 64 engages with the groove upper wall 45a of the lower horizontal frame.
Or, it is difficult to hit the pin 52a, and the rotation can be facilitated.

Further, the width of the downward groove 41 is made wider by making the width of the upper groove wall 41a shorter than the groove bottom wall 41b, and the width of the upper groove wall 51a is made shorter by making the width of the upper groove wall 51a shorter than the groove bottom wall 51b. The frontage is widened. Similarly, the width of the groove upper wall 45a is made shorter than that of the groove bottom wall 45b to increase the upward groove 45b.
The width of the upward groove 52 is made wider by making the width of the groove upper wall 52a shorter than the groove bottom wall 52b. Therefore, also in these respects, when mounting the solar cell module 30 by the karmic method, the groove upper wall 4
1a, 45a, 51a, and 52a can be prevented from being caught by the solar cell module 30. In particular, as described above, the insertion angle between the roof surface and the solar cell module 30 when the solar cell module 30 is inserted in the direction of arrow C as described above. It is possible to make the first insertion projection 71 into the downward grooves 41 and 51 more easily.

Further, since the terminal box 62 is provided on the back surface of the solar cell module 30 so as to be close to the upper frame member 63 side, when the solar cell module 30 is installed, the upper frame member 63 always faces upward. It is necessary to install it.
In this case, since the first insertion projection 71 longer than the second insertion projection 75 of the lower frame 64 is projected from the upper frame 63, the solar cell module 30 can be easily marked by using the first insertion projection 71 as a mark.
Can be determined. For this reason, there is little possibility that the solar cell module 30 is installed and installed in an incorrect direction.

Therefore, the above-mentioned stiffening work can be facilitated for the above reasons.

The upper frame member 63 of each solar cell module 30 attached according to the above-described procedure has the first insertion convex portion 71 having the groove upper wall 41a of the downward groove 41 or the groove upper wall 51a of the downward groove 51 of the upper horizontal frame member. And the lower side 63a is placed on the groove bottom wall 41b of the downward groove 41 or the groove bottom wall 51b of the downward groove 51,
The upper frame member 63 is restrained from moving in the thickness direction. In this case, since the rubber plates 72 and 73 are sandwiched between the upper frame member 63 and the downward grooves 41 or 51, it is possible to prevent the solar cell module 30 from rattling in the thickness direction. Similarly, the lower frame member 64 is positioned so that the second insertion protrusion 75 is hooked on the groove upper wall 45a of the upward groove 45 or the groove upper wall 52a of the upward groove 52 of the lower horizontal base. Since the portion 64a is placed on the groove bottom wall 45b of the upward groove 45 or the groove bottom wall 52b of the downward groove 52,
The lower frame member 64 is restrained from moving in the thickness direction. Also in this case, since the rubber plate 76 is sandwiched between the lower frame member 64 and the upward groove 45 or 52, it is possible to prevent the solar cell module 30 from rattling in the thickness direction.

Therefore, the solar cell module 30 is prevented from coming off from the space between the horizontal mounts adjacent to the roof 21 in the eaves direction. Moreover, the upper frame member 63 and the lower frame member 64 of the solar cell module 30 are pressed from above by the frame member pressing portion 81 of the pressing member 32 attached to each of the horizontal mounts 26 to 29. In addition, the holding members 32 can more reliably prevent the solar cell module 30 attached over the horizontal frame adjacent in the eaves ridge direction from coming off, and can improve the installation strength of the solar cell module 30. In addition, since each holding member 32 is provided so as to cover the entire upper surface of each of the horizontal frames 26 to 29 to which it is attached, the upper shape of each of the horizontal frames 26 to 29 affects the appearance of the power generation device 25. The appearance of the power generation device 25 can be improved by preventing the occurrence of the influence.

As described above, a group of solar cell modules 30 installed on the roof 21 and arranged in the longitudinal direction of the horizontal mounts 26 to 29 is connected to the stoppers 3 arranged on both sides of the group.
3, since it is possible to simultaneously stop the movement in the longitudinal direction of the horizontal mounts 26 to 29, it is not necessary to stop all the solar cell modules 30 individually. For this reason, the number of screwing points and fixing parts in installing the power generation device 25 can be significantly reduced.

Therefore, according to the installation work of the power generation device 25, as described above, the mounting work is facilitated by the tentative method of each solar cell module 30, and the necessary screwing work is greatly reduced. Because it can be reduced
The workability of installing the power generation device 25 on the roof 21 can be improved.

In the configuration of the power generating device 25, as described above, the upper frame member 63 of the solar cell module 30 does not need to insert the entire thickness into the downward grooves 41, 51 of the upper horizontal base, and Since it is not necessary to insert the entire thickness of the side frame member 64 into the upward grooves 45, 52 of the lower horizontal frame, the downward grooves 41, 51 and the upward grooves 45, 52 are not necessary.
Can be smaller than the thickness of the solar cell module 30. Therefore, the height of the horizontal frames 26 to 29 having these grooves can be reduced, and accordingly, the material cost of the horizontal frames 26 to 29 can be reduced, and the cost of the power generation device 25 can be reduced.

In addition to the fact that the number of fixing parts such as screws required for installing the power generation device 25 can be greatly reduced as described above, the number of operations for fixing the power generation device 25 to the roof 21 is also reduced. Therefore, the installation cost of the power generator 25 can be reduced in this respect as well.

Further, the power generation device 25 has an auxiliary rail 31 for fixing the solar cell module 30 to the roof 21 across the back side thereof, and the rail 31 supports the central part of the solar cell module 30 in the eaves ridge direction. Because
Withstand pressure performance against wind pressure applied downward to the solar cell module 30 during strong winds can be improved. Therefore, it is not necessary to obtain the pressure resistance performance with the side frame members 65 and 66 of the solar cell module 30 itself.
6, the height (the thickness in the vertical direction) of the upper and lower frame members 63 and 64 can be reduced. Therefore, the frame that defines the thickness of the solar cell module 30 can be reduced, and the solar cell module 30 can be reduced in thickness. Therefore,
The cost of the solar cell module 30 can be reduced, and the horizontal mounts 26 to 29 can each be reduced in thickness as the thickness of the solar cell module 30 is reduced, so that the cost reduction can be promoted. Therefore,
Also in this respect, the cost of the power generator 25 can be reduced.

Further, in addition to the solar cell module 30 being mounted in a swift manner and not being stacked and installed on each of the horizontal mounts 26 to 29, the solar cell module 30 and each Since the horizontal mounts 26 to 29 can be reduced in thickness, the installation height of the power generator 25 on the roof 21 can be reduced. Therefore, the step between the roof 21 and the power generator 25 installed thereon is reduced, and the appearance of the power generator 25 installed can be improved. In particular, the installation height G of the power generator 25 of the present embodiment on the roof 21 (see FIG. 2)
Is constructed to be as thin as about 40 mm with respect to the upper surface of the roofing bar 22. Therefore, when a Japanese roof tile is installed around the power generation device 24, the upper end of the Japanese roof tile and the upper end of the power generation device 25 are connected. The height can be made substantially the same, which can greatly contribute to improving the appearance of the roof 21.

It is superior to the first embodiment in the following points.

In the second embodiment, the groove bottom wall 4 of the lower horizontal base
5b and 52b are made to protrude greatly toward the ridge side, and the distance L from the groove depth surfaces 41c and 51c of the downward grooves 41 and 51 of the upper horizontal gantry to the ridge-side end of the groove bottom walls 45b and 52b of the lower horizontal gantry.
Is shorter than the length M from the tip of the first insertion projection 71 of the solar cell module 30 to the root of the second insertion projection 75. Therefore, in the installation work of the solar cell module 30 by the kendon method, in a state where the upper frame member 63 of the module 30 is inserted into the downward grooves 41 and 51 of the upper horizontal stand, the solar cell When rotating the module 30 toward the lower horizontal frame, the lower frame member 64 does not catch on the groove bottom walls 45b and 52b of the lower horizontal frame, and the groove bottom wall 45b of the lower horizontal frame is not caught. , 52b can reliably mount the lower frame member 64 of the solar cell module 30.

In addition, insulated wires 94 of substantially the same length,
Since 95 is divided and attached to the upper and lower portions of the side frame members 65 and 66, the male and female connection terminals 98 and 100 can be connected at substantially the center of the side frame members 65 and 66 in the longitudinal direction. Therefore, although the insulated wires 94 and 95 have the length for this connection operation, the sagging of the wires in the connection completed state can be reduced.

Incidentally, when the insulated wires 94 and 95 are provided at the point symmetric positions as described above, the side frame members 65 and 66 are used.
There is also an option to set the center in the longitudinal direction. However, in this case, the length of the insulated wires 94 and 95 required for the connection operation of the male and female connection terminals 98 and 100 becomes slack as it is. Large sag.

The tip of the screw 92 pushes downward the convex base 75a of the second insertion convex part 75 of the solar cell module 30 inserted into the upward grooves 45, 52, and the solar cell module 30, The lower frame member 64 is firmly sandwiched between the groove bottom walls 45b and 52b. Thereby, rattling of the solar cell module 30 can be prevented.

Further, the screw 92 inserted as described above is used.
Are arranged so as to be hooked on the rising portion 75b rising from the convex base 75a. Therefore, as the screw 92 is screwed in, an upward force is applied to the lower frame member 64,
Even if the solar cell module 30 moves to the ridge side,
Immediately, the rising portion 75b is caught by the screw 92, and the movement can be prevented. Therefore, it is possible to reliably prevent the solar cell module 30 from rattling by inserting the screw 92. Even if the solar cell module 30 is moved in the ridge direction for some reason such as wind pressure or vibration after the screwing, the movement is hindered by the screw 92 and the rising portion 75b being caught, and The module 30 can be maintained in a proper installation state.
